Karlijn Keijzer, 25, was a doctoral student in the chemistry department of the university's College of Arts and Sciences. She also was a member of the women's rowing team in 2011.

The school said she had been home for a brief summer vacation.

“Karlijn was an outstanding student and a talented athlete, and her passing is a loss to the campus and the university,” Indiana University President Michael A. McRobbie said in a statement. “Our hearts also go out to the families of all the victims of this senseless act.”

Mu-Hyun Baik, an associate professor of chemistry and informatics, was Keijzer's doctoral adviser.

Keijzer "worked on several research projects, all related to improving human health,” Baik said in the statement. “The last piece of research work she completed before heading out to catch her flight to her short summer vacation was preparing a computer simulation on bryostatin, an anti-cancer drug and a promising drug candidate for treating Alzheimer's disease.”

Keijzer was a member of the university's Varsity 8 boat, helping them to a 14-5 record during the 2011 season. She participated in the European Rowing Junior Championships in 2006 and the World Rowing Junior Championships in 2007.

“Karlijn was the ‘stroke' of the Varsity 8 boat for us,” Indiana head rowing coach Steve Peterson said in the statement. “That is the person who sets the rhythm for the boat and everyone follows her. She was unquestionably the leader of the best boat we had that year. It was the first boat that got us into the national rankings and had a great season.”
